Apple is looking to the next generation of its iPhones with the iPhone 6, the sixth iteration of the smartphone with an all-new design and a faster processor.

Apple CEO Tim Cook told the Wall Street Journal in an interview that the next iPhone should be “the best-designed iPhone ever.”

“It has a better display, it has a new camera, it’s a better processor, it does a lot more with a bigger battery, it is thinner,” Cook said.

The iPhone 5s is the only iPhone 6 to feature a metal frame and a glass back, though the iPhone 5S was a bit smaller than the 6s.
